Issues that I've noticed: - With ~100 groups of elements: "attach" action makes the app freeze - With many cut and draw elements: there is no way to maintain those on import(?), so it's a pain to select each one to set the pen color / tool - \`transform="translate(-10, 0)"\` switches x and y, moving elements up instead of left 😶 - Some combination of \`translate\` and \`scale\` gets... lost... in _translation_ 😏 Cricut's software and file format are closed-source, so I was losing hope that I could work with my generative designs. Then, I got this idea. It seems like it can handle small numbers of big paths. What if I brute-force the design down to one path per tool? This is an attempt to "compile" SVG paths for CNC software down to basic X/Y movements. Each combination of stroke and fill becomes one path element. This makes it easier to attach them in Cricut, and then set the tool for each layer. ~~File size is much larger.~~ _(Edit: fixed that with smarter flattening.)_ Cricut doesn't choke. Success! (Seems like they could make this an option when importing. 🤔) Tested with a [moderately complex SVG](https://observablehq.com/@forresto/moon-grid), and it's much easier to work with. ## Cricut/SVG Tips 1 inch = 72px, so you can design with a function like this: ~~~js function inch (n) { return n * 72 }; inch(8.5); // 612 inch(2); // 144 inch(1/2); // 36 inch(1/4); // 18 ~~~ If designing for a specific size paper, make **registration marks** in a color that you won't use. Make them 1/4 inch from each corner. This should make the output centered as you expect. When Cricut asks you to insert that color pen, press "Go" without a pen in the holder. Set SVG width and height to inches, and viewBox to pixels: ~~~svg
